Controller Based Network Resource Management

1. A method of network controller based network resource management, comprising: receiving a flow at a network controller; determining a flow parameter for the flow; determining, via the network controller, an idle timeout for a flow rule, corresponding to the flow, based on the flow parameter, wherein determining the idle timeout for the flow rule includes: determining a previous idle timeout for the flow in response to determining that the flow has been received before, setting the idle timeout to a temporal value based on the flow parameter in response to the previous idle timeout being less than a second value, wherein the second value is greater than a first value, determining an activity factor for the flow rule in response to the previous idle timeout being greater than or equal to the second value, setting the idle timeout to the second value in response to the activity factor being less than a threshold, and setting the idle timeout to the first value in response to the activity factor being greater than or equal to the threshold.

2. The method of claim 1 , wherein the activity factor is determined based on active time of the flow rule and the previous idle timeout.

3. The method of claim 1 , wherein the first value is a minimum idle timeout and the second value is a maximum idle timeout.

4. The method of claim 1 , wherein the first value is selected as one hundred milliseconds and the second value is selected as ten seconds.

5. A method of network controller based network resource management comprising: receiving a flow at a network controller; determining, via the network controller, an idle timeout for a flow rule, corresponding to the flow, based on a flow parameter; determining a network memory parameter; evicting the flow rule from network memory in response to the network memory parameter being greater than an eviction threshold; setting the idle timeout for the flow rule to a first value in response to determining that the flow has not been received before; determining a previous idle timeout for the flow in response to determining that the flow has been received before; setting the idle timeout to a temporal value based on the flow parameter in response to the previous idle timeout being less than a second value; determining an activity factor for the flow rule in response to the previous idle timeout being greater than or equal to the second value; setting the idle timeout to the second value in response to the activity factor being less than a threshold; and setting the idle timeout to the first value in response to the activity factor being greater than or equal to the threshold.
